They are not going to let you refinance from 180k in debt to 150k in debt.

Your debt to income eventually maxes out!

You have a lot of debt to pay off and that income will finance your real estate.

On an individual basis, I have a credit score over 800 with revenue already being created and have very little debt.

I'm pretty inexpensive (about half compared to typical small firms) because I also work full time as an attorney, and merely practice on the side to assist with my real estate deals and pay down law school debt (which is mortgage-sized), but I'm also very good (graduated with honors, guest lecturer, published papers, etc). 

I'm not too sure on what you're asking, but if you are in the process of applying for a mortgage your lender will be very unhappy if you open new debt during the process.

This is pretty standard with owner carry contracts anyway.2) The use of debt-financing will expose your IRA to taxation known as UDFI.  

Having all personal debt paid off will help you get a loan also. 

I'd take a hard look at the budget and takes steps to eliminate and minimize all re-occurring expenses.
